## The airworthiness directive

76-13-12 BRITTEN-NORMAN LTD: Amendment 39-2660. Applies to Islander Models BN-2, BN-2A, BN-2A-2, BN-2A-3, BN-2A-6, BN-2A-8, BN-2A-9, BN-2A-20 and BN-2A-21 airplanes, certificated in all categories, which incorporate Britten-Norman Modification No. NB/M/430.

Compliance is required within the next 100 hours time in service after the effective date of this AD, unless already accomplished.

To prevent inadvertent retraction of the flaps beyond the normal 6 degree droop position, accomplish the following:

  (a) Perform a visual inspection of the flap retract position in accordance with the Inspection paragraph of Britten-Norman Service Bulletin No. BN-2/SB.66, dated August 3, 1973, or an FAA-approved equivalent.

  (b) If the flap retract position is found to be out of tolerance, before further flight, adjust the flap actuator in accordance with Rectification paragraphs 1, 2, 3, and 4 of Britten-Norman Service Bulletin No. BN-2/SB.66, dated August 3, 1973, or an FAA-approved equivalent.

NOTE: Material L65, specified in Fig. 1 of Britten-Norman Service Bulletin No. BN-2/SB.66, dated August 3, 1973, is the same as Alum. Alloy U.S. QQA-261 (AL 14S).

This amendment becomes effective July 15, 1976.
